Water Facts Over the past five years, municipal water rates have increased by an average of 27 percent in the United States, 45 percent in Australia, 50 percent in South Africa, and 58 percent in Canada. In Tunisia, the price of irrigation water increased forufold over a decade.Yet consumers rarely pay the actural cost of water. The average distance that women in developing countries walk to collect water per day is four miles and the average weight that women carry on their heads is approximately 44 pounds. (WSSCC, 2004). * Over 40 billion work hours are lost each year in Africa to the need to fetch drinking water.

- One irrigation cycle can be divided by the assumed 90 minutes of irrigation to acquire the minutes per a gallon for an irrigation cycle. This value also assumes that a rain sensor shut device is present. 300 gallons per single family household per day × 7 days = 2100 gallons per week. 2100 gallons per week / 2 irrigation cycles = 1050 gallons per irrigation cycle. 1050 gallons per irrigation cycle / 90 minutes = 11.67 gallons per minute per irrigation cycle. 2 Southwest Florida Water Management District, 2008.

Typical household water consumption June 9, 2013 at 6:30 pm. The amount of 7500 is the volume of water that one person would use should they use 250 litres of water a day. Every household receive 6000 litres of free water per month. Regarding toilet flushing; modern toilets are fitted with 9 litre cisterns or even 6 litre cisterns, however the bulk of older homes in South Africa still have 13 litre cisterns. This then works out to 5.5 flushes a day which is seen as typical.

Water Access in South Africa Currently, South Africa has access to surface water (77 percent of total use), groundwater (9 percent of total use), and recycled water (14 percent of total use) [1]. However, the population’s dependence on water is not evenly distributed.inally, South Africa’s industry sector, which contributes about 29 percent of the nation’s total GDP, uses almost 11 percent of the nations water [1]. However, because a large portion of South Africa’s industry sector is in mining, the sector’s impact on water goes far beyond 11 percent a year.

Landscape Irrigation Management Part 3: How Much Water? An average household in South Carolina will use 120 to 150 gallons of water per person per day. Using the 150 gallon per person per day figure, a four person household may use (150 gallons of water per person x 4 persons x 7 days =) 4,200 gallons of water each week. When a homeowner applies one inch of water each week to a one acre landscape, the homeowner uses 27,154 gallons of water.

- Some tap and natural water may have a slight brown tinge from humic acid, which is harmless and does not affect drinking water quality in South Africa. The market for bottled water is growing in South Africa, and supermarket shelves hold numerous brands, some of them well-known international names.n some areas South African drinking water is rich in minerals and may involve a bit of getting used to. Avoid drinking water from streams and rivers, especially in areas where there is human habitation. These may carry water-borne diseases.

CHAPTER 4 - RAINFALL AND EVAPOTRANSPIRATION 10 mm rainfall on the field. In terms of volume, with a rainfall of 10 mm, every square metre of the field receives 0.01 m, or 10 litres, of rain water. With a rainfall of 1 mm, every square metre receives 1 litre of rain water.A rainfall of 1 mm supplies 0.001 m 3, or 1 litre of water to each square metre of the field..1.2 Rainfall intensity. The rainfall intensity is the depth of water (in mm) received during a shower divided by the duration of the shower (in hours). It is expressed in millimetres of water depth per hour (mm/hour).

Ogallala Aquifer could dry up in 50 years The findings showed that by 2010, 30 percent of the aquifer's water had been used. If current usage continues, an additional 39 percent of water is expected to be tapped by 2060 resulting in the loss of 69 percent of the aquifer's total groundwater.rofessors at Kansas State University have found that the Ogallala Aquifier, which covers 30 percent of the United States' irrigation needs, could be mostly depleted by 2060 if current trends continue.

Drying times: Could the rapidly depleting Ogallala Aquifer run dry? The Ogallala Aquifer across the region has dropped about 325 billion gallons every year for at least the past four decades. To put that number into perspective, the roughly 1-foot annual drop in the aquifer is more than enough to supply all of Lubbock’s municipal water needs for 25 years.You’re still using water at a much faster rate than it’s being recharged.”. Rapidly declining. That nearly 45 million-acre-foot decline in the Ogallala Aquifer equates to about 14.6 trillion gallons of water over 45 years.

Sterkfontein Dam The dam receives its water via the Tugela-Vaal Project which is a pumped-storage scheme involving the net transfer of up to 630 million cubic metres (510,000 acre·ft) of water from KwaZulu-Natal. This is stored in the Sterkfontein Dam and released to the Vaal Dam via the Wilge River when needed.he Sterkfontein Dam is a highly effective reservoir, since it has the depth to store a large amount of water, with very little loss to evaporation. The Vaal Dam lake (reservoir) by comparison has a large surface area and is relatively shallow, which results in a higher rate of evaporation.
